论文摘要
本文介绍了对产生超快强烈红外（IR）脉冲的双晶格光学参数扩增（DC-OPA）方案的优化。通过使用0.77 J TI的总能量：蓝宝石泵激光器和I型BBO晶体，使用优化的DC-OPA，中心波长的IR脉冲能量超过0.1 j。通过调节以上超过70 \％的总吞吐量的注入的种子光谱和棱镜对压缩机，将1.7- $ m $ m脉冲压缩至31 fs，从而导致高达2.3 TW的峰值功率。根据BBO型I型DC-OPA的演示，我们提出了一种新颖的OPA方案，称为$ Dual〜Pump $ dc-Opa，用于生产具有两循环持续时间的高能量IR脉冲。
This paper presents the optimization of a dual-chirped optical parametric amplification (DC-OPA) scheme for producing an ultrafast intense infrared (IR) pulse. By employing a total energy of 0.77 J Ti:sapphire pump laser and type-I BBO crystals, an IR pulse energy at the center wavelength of 1.7 $μ$m exceeded 0.1 J using the optimized DC-OPA. By adjusting the injected seed spectrum and prism pair compressor with a gross throughput of over 70 \%, the 1.7-$μ$m pulse was compressed to 31 fs, which resulted in a peak power of up to 2.3 TW. Based on the demonstration of the BBO type-I DC-OPA, we propose a novel OPA scheme called the $dual~pump$ DC-OPA for producing a high-energy IR pulse with a two-cycle duration.
